Observability, Monitoring & Debugging

These libraries track performance, exceptions, and trace logs in deployed AI applications. Ideal for SaaS AI tools, LLM agents, and long-running model services.

Tools:

• Rerun – Visualization tool for AI observability, supporting embeddings, images, and event logs. Great for debugging perception models.

• Sentry Python SDK – Monitors app crashes, performance issues, and errors. Integrates well with FastAPI, Flask, Django, and Celery.

• Loguru – Simple logging utility with beautiful formatting, easy rotation, and exception catching. Cleaner alternative to logging.
